Решение уравнений в) 1/2(4-3 целых 1/2х)=1 целая 1/4х-1/2. ,

В) 1/2(4-3 целых 1/2х)=1 целая 1/4х-1/2

1/2•4 - 1/2• 3 1/2х= 1 1/4х -1/2

2- 1/2• (2•3+1)/2Х= (4•1+1)/4Х- 1/2

2- 1/2• 7/2Х=5/4Х -1/2

2- 7/4Х = 5/4Х -1/2

2+ 1/2= 5/4Х+ 7/4Х

2 1/2= 12/4Х

2 1/2= 3Х

Х= 2 1/2 : 3

Х= (2•2+1)/2 • 1/3

Х= 5/2• 1/3

Х= 5/6

1/2•(4- 3 1/2• 5/6) =1 1/4• 5/6 -1/2
1/2•(4 -(3•2+1)/2• 5/6)= (4•1+1)/4• 5/6-1/2

1/2• (4- 7/2• 5/6)= 5/4• 5/6 -1/2
1/2• (4- 35/12)= 25/24- 1/2
1/2• (4- 2 11/12)= 25/24- (1•12)/(2•12)
1/2• (3 12/12- 2 11/12)= 25/24- 12/24
1/2• (1 1/12)= 13/24
1/2• (12•1+1)/12= 13/24
1/2• 13/12= 13/24
13/24= 13/24.
